If you recall, the update - which is currently rolling out over-the-air (OTA) - was originally supposed to be outed by the end of February. So, it has arrived a bit late, but arrived nonetheless.

Given the fact that the roll-out has just begun, it may take some time before the update hits your device. However, if you're feeling impatient, you can also manually check for it by heading to your device's Settings menu.
